How to develop a test class

Hello everyone, I successfully create a form of record views of users and now cannot deploy in my production org without a test class. I've searched all day for a sample test that can help explain what I am to do, no luck!

Here is my class code:
  
public class lastViewed{
 
    public Datetime cDT; 
    public String LongDate; 
    public String firstname; 
    public String lastname;    
    public String userid;
 
    private final Chalkboard_Manager__c acct;
 
    public lastViewed(ApexPages.StandardController stdController) {
        this.acct = (Chalkboard_Manager__c)stdController.getRecord();    }
 
                public String getLongDate() {        
                cDT = System.now();        //Format the datetime value to your locale        
                LongDate = cDT.format('dd/MM/yyyy HH:mm');    return LongDate;    
            }
 
        public void updateField() {
        //Get the user info from the current user        
    firstname = System.Userinfo.getFirstName();        
    lastname = System.Userinfo.getLastName();       
    userid = System.Userinfo.getUserId();
 
        //Get the chalkboard record to be updated        
    Chalkboard_Manager__c a = [select Last_Viewed_By__c from Chalkboard_Manager__c where id = :acct.id limit 1];        
 
    //Assign values to Last Viewed By field & update the record        
    a.Last_Viewed_By__c = (firstname + ' ' + lastname + ', ' + getLongDate());        
    update a;    
    }
 
}

Hi Sara,

Please check sample code below :  


@isTest
private class lastViewed_Test{
  @testSetup
  static void setupTestData(){
    test.startTest();
    Chalkboard_Manager__c account_Obj = new Chalkboard_Manager__c(Name = 'Name796', Last_Viewed_By__c = '36');
    Insert account_Obj; 
    test.stopTest();
  }
  static testMethod void test_getLongDate_UseCase1(){
    List<Chalkboard_Manager__c> account_Obj  =  [SELECT Id,Name,Last_Viewed_By__c from Chalkboard_Manager__c];
    System.assertEquals(true,account_Obj.size()>0);
    lastViewed obj01 = new lastViewed(new ApexPages.StandardController(account_Obj[0]));
    obj01.cDT = DateTime.now();
    obj01.LongDate = 'test data';
    obj01.firstname = 'test data';
    obj01.lastname = 'test data';
    obj01.userid = 'test data';
    obj01.getLongDate();
  }
  static testMethod void test_updateField_UseCase1(){
    List<Chalkboard_Manager__c> account_Obj  =  [SELECT Id,Name,Last_Viewed_By__c from Chalkboard_Manager__c];
    System.assertEquals(true,account_Obj.size()>0);
    lastViewed obj01 = new lastViewed(new ApexPages.StandardController(account_Obj[0]));
    obj01.cDT = DateTime.now();
    obj01.LongDate = 'test data';
    obj01.firstname = 'test data';
    obj01.lastname = 'test data';
    obj01.userid = 'test data';
    obj01.updateField();
  }
}



Hope this helps you.
Please let me know in case of any other assistance.

The test class you need to create, when it is run, will call your lastViewed class and should cause at least 75% of its code to excute without causing any errors. This should get you started learning how to create them:

If you're on Trailhead though, you might want to start here:
